I remember seeing some celebrities in the late 00s / early 10s with IR-emitting sunglasses or accessories to flood the camera sensors of paparazzi and make it harder for photographers to get spyshots of them. Would this approach work for these camera glasses as well, simply flooding them with so much IR spectrum light that their sensors simply can't see you anymore?

I have been thinking of a device to thwart license plate readers by dumping a ton of IR and/or visible light on the plate before it gets read. Perhaps combined with some reflective coating? Retroreflectors are promising

Repo men use those readers to track cars to be repossessed. And as it happens, it is very successful industry these days.

Putting myself in the shoes of a qa for a second... What is the cheapest way for me to trigger a false positive on such a detection device? And what can we do about it? Rinse and repeat until the cheapest cost exceeds a standard pair of smart glasses.

Before putting yourself in the mind of QA, you have to be 100% sure on what the goals and priorities of the product is supposed to be in the first place.

Only a subset of use potential cases will be worried with false positives, but this approach says to drive the cost greater for all potential use cases.

Have you thought about the potential eye/skin damage you would be causing with IR LEDS.

Potentially as much as none, because it's UV that does the damage?

At some point it pretty much becomes a microwave. Radiation get absorbed and turned into heat. On a small scale not very helpful or harmful. On a larger scale nice to heat your food with but not your head.

Short answer is its complicated and will vary from member state to member state. My parental unit had a dispute with neighbor over where his camera is pointed and filed some motion to see what he does with it ( 'not making a database' part ), but the law was mostly toothless as the enforcement of it lacked. On the other hand, the dispute part of the real estate was handed real toot sweet, because everyone and their m…

It might be in the original French, but it’s been anglicised and adopted as an English language term:

It is interesting to see the consensus that nobody is enthusiastic about meta Ray-Bans except Zuckerberg. It's creepy.

The only real usage I've seen is on Instagram reels etc. where people are using them in red light districts like in Amsterdam to film the women.

Well, there's https://www.nii.ac.jp/userimg/press_details_20121212.pdf I think fooling facial recognition systems and CCTV-cameras-at-night is easier than fooling professional photographers. Most photograhers' cameras have IR filters, after all. And nobody's got an LED brighter than the sun.

On this topic, is there any benefit of trying to fool facial recognition systems with these type of accessories and or wearables, would the system not just mark you as suspicious and keep an even better track of you Of course it is a different thing if these are adopted by the masses

Usually those systems are set up to track faces and/or people, and ignore everything else. If you get a low-confidence detection of a face that's much more likely to be a dog or a band t-shirt than somebody tricking your system. So you would typically ignore everything below a threshold, not flag it.

You could train a system to detect these kinds of attacks, but that's a lot more sophistication that these types of systems usually have, and would probably be specific to each "attack" (e.g. those glasses with lights would look completely different than the face paint approach)

The best defense would be a human watching the raw camera feed, since most of these attacks are very obvious to the human eye. But that's expensive. Maybe you could leverage vision-llms, but those are much more expensive than dedicated face-detection or object classification models. Those typically range from sub-million to maybe a hundred million parameters, while you need billions of parameters for a good vision-llm

Interesting idea. It seems to me that most things which would need to be protected from hidden cameras would be stationary and not require the operator to mount the detectors on his body, but starting with mobile constraints is often helpful. I would like to draw attention to this gem of wit, easily the best I've seen in a long time: > I think the idea behind this approach is sound (actually it's light)

I love this way English has of swallowing and digesting terms from other languages. https://www.oed.com/dictionary/the-tooter-the-sweeter_phr
